Hello, I'm tried booting linux 2.4.3 on my prototype system which does not have a keyboard and a monitor. I used the uart as my serial device and passed on the console=ttyS0(com1 in my pc) to the kernel. I can see the shell prompt after the kernel bootup but not able to enter anything after that. So how can I use my pc keyboard to send characters to my uart? I think I'm missing something here. Can anyone give me some hint? Thankyou in advance... regards, Balaji
